I've not long installed SpywareBlaster and haven't updated it yet, the 'check for updates' link doesn't take me anywhere, and the site it does say to visit doesn't appear to have updates, just new versions. What's the procedure install new version over the top of old version or delete old version and install new? Thanks TR
